METHOD OF MAKING DECORATIVE MATERIAL FROM PEAT.

No Drawing. Application filed Julie 1, 1926, Serial No. 113,075, and in Netherlands May 30, 1925.

Various processes are known, in which peat is pulverized or disintegrated and, if necessary deacidified and compressed in the dry or wet condition with the addition of binding substances, impregnating bodies or other materials, such as gypsum, sulphur, loam, clay, calcareous sandstone, resin, alcohol, glue, tar, water glass, etc. According to all these known processes the natural fibrous structure of the peat is destroyed, so that the products (for instance, plates or the like) obtained by such processes exhibit a uniform or almost uniform coloration.

' he process according to the present invention is characterized by the feature, that pieces. of natural bog deposit or peat ranging from 8 to 8000 cubic-centimetres in size are first dried out until their water content is 10% or less and are then compressed at a pressure of from to 300. atmospheres.

The plates or other objects produced in this way may be polished, rubbed down, burnished or, it desired, coated with impregnating substances.

25 The object of the process according to the present invention is to obtain an artdecorative material of .great- -architectural value. In consequence of thevarying runs of the fibres the products obtained have a \vonderfi'll color gradation or graining ettect (light and shade effect), while the cost of these products is very low as afresult'of the cheapness of the raw materials and the inexpensive method of manufacture.

The art-decorative products obtained in this way may be used as a covering for walls,

and interlace With .ing

floors and ceilings, or for the manufacture o'f'objects of art, etc. 1

The process is carried out in the following manner.

The pieces of bog deposit of peat are cut in sizes ranging from 8 to 8000 cubic centimetres and are then dried either by natural or artificial means until the water content is-10% or less. The dried pieces are then 4 introduced 1nto the press without the addition of any binding or other substance so, that the fibres extend in various directions one another. The material is then pressed into the desired shape at a temperature of 40200 C. and a pres sure of 25-300 atmospheres.

The pressure. is dependent on the purpose for which it is desired to employ the pressed material.

I claim as my invention:

A process for the production of decorative materials from pieces of peat or bog deposit hav ng long fibres,

comprising the successive steps of drying raw pieces of peat or ho; in their original state to reduce their water-content to about 10%, and then press said pieces directly togethcn. so as. to consolidate them into a single integral mass or :object of extreme firmness and density and of the desired size in which the fibres extend in various directions throughout the mass and are caused toin'terlace with one another.

In testimony whereof I affix my signature.
